Olive oil can constrict the blood vessels that can contribute to heart disease.
Best Heart Benefits From Canola and Fish Oils -- Not Olive Oilhttp://connecticare.com/GlobalF.../HealthNews/article.asp...
"The olive oil meal caused vessels to constrict by 34%, whereas the canola oil and salmon meals caused insignificant changes in blood vessels, Vogel reports. Because such constrictions injure the blood vessels' endothelium, they contribute to heart disease."
Correlation Analysis of Cocoa Consumption Data with Worldwide Incidence Rates of Testicular Cancer and Hypospadias
"This correlation analysis suggests that cocoa consumption during early life might be correlated to both TC incidence among young men aged 20–34 years and hypospadias, a reproductive congenital defects supposed to underline the same pathogenetic mechanism of TC.
In particular, the increasing incidence of TC over time in developed countries is consistent with increases in the consumption of cocoa. The intake of some of the main sweet ingredients, in fact, such as cocoa and sweeteners increased significantly during the last 45 years in developed countries [8,9]. Over the years 1961–2004 cocoa consumption overall in developed countries grew at an average rate of 1 % per year . For example, in Denmark cocoa consumption more than doubled in the period 1961–2004. Similar trends have been observed in other European countries [8,9]. The magnitude of these increases is similar to those noted for incidence rates of testicular cancer and other MRD. The reduced risk for testicular cancer for the cohorts of Danish, Norwegian, Swedish and Japanese men born during World War II is also consistent with a greatly reduced supply of sweet foods and cocoa during the war.
Data from food balance sheets (FAOSTAT) indicate that the consumption of cocoa in Denmark, where TC and hypospadias rates are elevated, is among the highest in the world and is more than three times that in Finland, where MRD rates are rather low .
Is there any evidence that this association may be causal?
Cocoa powder is a complex substance containing several biologically active compounds, including theobromine, caffeine, serotonin, phenylethylamine and cannabinoid-like fatty acids .
Various studies reported that theobromine, the main stimulant of cocoa, exerts toxic effects on the testis, inducing testicular atrophy accompanied by aspermatogenesis or oligospermatogenesis and that even low doses of cocoa impair sperm quality [10–14]."
oil-free salad dressings
Carotenoid bioavailability is higher from salads ingested with full-fat than with fat-reduced salad dressings as measured with electrochemical detection
The study found that salads eaten with 28grams of fat allowed for greater absorption of cartenoids such as vitamin A. 28 grams of fat is equivalent to 2 tablespoons of fat/oil.
Study: High Fructose Intake Linked to Slightly Higher Risk of Death
"those who consumed lots of liquid sugar—from sodas, sports drinks, juices, etc.—had higher odds of dying of any cause (from cardiovascular disease, in particular). Why? It could be because sugars from beverages are rapidly absorbed, resulting in significant blood-sugar spikes, the scientists say."
"While this study just proved association, not causation, scientists do have a theory: Fructose produces "advanced glycation end-products," or AGEs, which may damage the walls of your arteries, encourage bad cholesterol to hang around"
"You don't, of course, have to give up fruit, which is a staple of any well-balanced diet. But you may want to cut back on your intake of other sources of fructose: fruit juices, soft drinks, preserves, applesauce, dried fruit, and candies."
